The owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb. He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb. How many pounds of each should the owner use?
_ pounds of chocolate candies
Answers
Answer:
9 pounds of chocolate candies
6 pounds of sugar candies
Step-by-step explanation:
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 * 5 = 75
7x + 2 * (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
15 - 9 = 6
y = 6
9 pounds of chocolate candies and 6 pounds of sugar candies
The owner should use 6 pounds of the chocolate candies, and the other 9 pounds of the sugar candies.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb.
He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb.
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 x 5 = 75
7x + 2 (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
Now 15 - 9 = 6
y = 6
Threfore, we conclude that 9 pounds of chocolate candies and 6 pounds of sugar candies.

Write the equation of the line that passes through the given points.
(15/8,0) and (17/8,1/2)
The equation of the line is _______.
Answers
Answer:
Step-by-step explanation:
Going from (15/8,0) to (17/8,1/2), we see that x (the 'run') increases by 2/8, or 1/4, and that y (the 'rise') increases by 1/2. Thus, the slope of this line through the given points is m = rise / run = (1/2) / (1/4) = 2.
Using the point-slope formula for the equation of a line, we obtain:
y - 0 = 2(x - 15/8), or
y = 2(x - 15/8) (simplest form), or
8y = 2x - 15/4, or
2x - 8y = 15/4, or
8x - 32y = 15
All of these are correct; they are 'equivalent.'

You start hiking at an elevation that is 80 meters below base camp.
You increase your elevation by 42 meters. What is the new elevation
with respect to base camp?
Answers
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since a negative value is below the base camp, this means that you are now 38 m below base camp.

We move -3 to another side and leave y as the subject of equation. Moving to another side will change the sign/operator to opposite.

Answers
Answer:
5.83
Step-by-step explanation:
Find the mean:
10(.1) + 15(.2) + 20(.2) + 25(.4) + 3-).1)
u = 21
Find the standard deviation:
[tex]\sqrt{(10 -21)x^{2} (.1) + (15 -21)x^{2} (.2)+(20-21)x^{2} (.2)+(25-21)x^{2} (.4)+(30-21)x^{2} (.1)}[/tex]= 5.83
The standard deviation is of 5.83.
The expected value is given by each value multiplied by it's relative frequency, thus:
[tex]E(X) = 0.1(10) + 0.2(15) + 0.2(20) + 0.4(25) + 0.1(30) = 21[/tex]
The standard deviation is given by the square root of the sum of the difference squared of each value and the mean, multiplied by it's relative frequency.
Then:
[tex]\sqrt{V(X)} = \sqrt{0.1(10 - 21)^2 + 0.2(15 - 21)^2 + 0.2(20 - 21)^2 + 0.4(25 - 21)^2 + 0.1(30 - 21)^2} = 5.83[/tex]
The standard deviation is of 5.83.

Step-by-step explanation:
So, Steve has $30, so you want to add that amount to the amount he earn, which is $105.
$5 times 21 is $105
h = 21
but we still need for m but, we already have m
m = $105

Answers
28 is the number of tickets of the second prize
How to calculate how many tickets the second prize is?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Given that:
The first time wins = 60 tickets
The second time, she won a bonus, which was 4 times the number of tickets of the second prize
Altogether she won 200 tickets
Let N represent the number of tickets of the second prize
This can be written as:
60 + N + (4×N) = 200
60 + N + 4N = 200
60 + 5N = 200
5N = 200 -60
5N = 140
N = 140/5
N = 28
Therefore, the number of tickets of the second prize is 28

john swims 5/12 of a mile in 3/8 of an hour. What distance, in miles, does john swims in an hour?
A.) 1 5/9
B.)15/96
C.)5/20
D.)1 5/12
Answers
Answer:
1 1/9 miles
Step-by-step explanation:
If john swims 5/12 of a mile in 3/8 of an hour, then;
5/12 miles = 3/8 hours
TO get the number of miles he swims in an hour, we will say;
x miles = 1 hour
Equating both expressions
5/12 miles = 3/8 hours
x miles = 1 hour
Cross multiply
3/8 x = 5/12
3x/8 = 5/12
3x * 12 = 5 * 8
36x = 40
x = 40/36
x = 10/9
x = 1 1/9
The amount he swims in an hour is 1 1/9 miles
